Yoyaku - Booking is an open-source booking engine designed for developers, agencies, and businesses that require a flexible system to manage appointments and services. It provides a foundation for handling client bookings, staff scheduling, and payments without proprietary restrictions.

Open-Source Foundation: Built as a fork of an established system, the code is fully available for inspection, modification, and distribution, giving developers complete control over their booking environment.

Service and Staff Management: Define multiple services with specific durations and pricing, and assign staff members to them to prevent scheduling conflicts and manage team capacity.

Customizable Booking Workflow: Add custom fields to capture specific client information and use hooks and filters to modify the booking process, enabling tailored experiences for different business needs.

Automated Notifications and Payments: Send automated email or SMS reminders to reduce no-shows and integrate payment gateways to allow clients to pay at the time of booking.

Developer-Focused Extensibility: A comprehensive API and built-in hooks allow for deep integration with external systems like CRMs, enabling the creation of custom modules and automated workflows.
